Description

一种离心式水泵 
技术领域
本实用新型涉及一种离心式水泵,具体地说是一种可以提高产品使用寿命的离心式水泵。 
背景技术
目前,现有的离心式水泵主要由外壳、定子组件、转子组件、电机轴、进水盖与泵叶组件组成,定子组件安装在外壳腔体内,电机轴安装在转子组件的中心位置处,转子组件位于定子组件的中心柱状腔体内。进水盖安装在外壳上,泵叶组件位于进水盖的腔体内,进水盖上设有进水口与出水口。定子组件位于一柱状壳体内,定子组件与壳体内壁之间的间隙为0.3~0.4mm,由于定子组件与壳体内壁之间的间隙非常小,水泵在使用一段时间后,水中的污垢将堵塞定子组件与壳体内壁之间的空隙,导致水泵不能再使用,另外,也会发出阵阵杂声,缩短水泵的使用寿命。 
发明内容
本实用新型的目的是提供一种可以提高产品使用寿命的离心式水泵。 
本实用新型的目的通过以下技术方案来实现。 
一种离心式水泵,包括外壳、定子组件、转子组件、电机轴、进水盖与泵叶组件,定子组件安装在外壳腔体内,电机轴安装在转子组件的中心位置处,转子组件位于定子组件的中心柱状腔体内;进水盖安装在外壳上,泵叶组件位于进水盖的腔体内,进水盖上设有进水口与出水口,其特征在于:所述泵叶组件与转子组件之间设有用于隔离水的隔水片。 
所述隔水片安装在电机轴上,隔水片与外壳之间设有密封圈。 
本实用新型与现有技术相比具有以下优点: 
本实用新型所述的离心式水泵由于在泵叶组件与转子组件之间设有 用于隔离水的隔水片,水通过进水盖上的进水口进入后,随泵叶组件中的叶轮转动而产生离心力,离心力使液体自叶轮周边抛出,汇成高速高压水流经进水盖上的出水口处流出,水将无法进入到电机定子组件与定子壳体之间的腔体内,从而避免水污垢堵塞定子组件与定子壳体内壁之间的空隙,提高了水泵的使用寿命。 
附图说明
图1为本实用新型离心式水泵的装配剖面结构示意图。 
具体实施方式
下面结合附图对本实用新型离心式水泵作进一步详细描述。 
如图1所示,本实用新型所述的离心式水泵主要由外壳7、定子组件5、转子组件6、电机轴8、进水盖1、泵叶组件3与隔水片4组成。外壳内为一圆柱状腔体,定子组件安装在腔体的内壁上,转子组件位于定子组件中的腔体内,电机轴安装在转子组件的轴心位置处。进水盖安装在外壳的顶部,进水盖内为腔体状,进水盖上设有进水口与出水口,进水口与出水口与腔体相通,泵叶组件位于腔体内。隔水片位于泵叶组件与转子组件之间,其周边与外壳的接触边缘处设有用于密封的胶圈,隔水片安装在电机轴上。泵叶组件安装在一泵叶轴支2上。电机带动电机轴转动,电机轴带动泵叶组件中的叶轮高速旋转,叶轮内的水被迫随叶轮转动而产生离心力,离心力迫使液体自叶轮周边抛出,汇成高速高压水流经进水盖上的出水口排出,叶轮中心处形成低压,从而吸入新的水流,构成不断的水流输送作用。
